Help Installing Rodi unit

[saixiong08]

So i purchased a rodi unit and it came in today, sadly there is no instructions on how to install it(membrane already been installed). I've looked online and kind of got it figured out but not 100% sure as how to do it. Theres a red, yellow, and black line. I think the red line is for the input, the black is for the drain, im not sure what the yellow tube is for... any ideas will greatly help.

On mine I have a red, blue, black line. The red is supply, the black is reject, the blue is ro out. Look at the lines. The red should be entering the first sediment filter. the black should be coming out of the end of the membrane along with another tube that goes to the di filters if you have them. The line coming out of the di filter is the water you want to use. A quick call to the manufacturer should be able to tell you if all else fails. The reject water will be several times the volume of the ro water that you will use. Simply put supply goes to the first filter. The membrane should have one line going in one end and two lines coming out of the other end. One of the two lines flows more water(the reject water), the second line in cleaned water that will be used or run through di resin for additional cleaning.
